You might also need to add one or more of these new roles to your SELinux user record.

List the SELinux roles your SELinux user can reach by executing:

$ semanage user -l |grep selinux_name

Modify the roles list and add sysadm_r to this list.

$ semanage user -m -R 'sysadm_r staff_r user_r' sysadm_u

For more details you can see semanage man page.

X WINDOWS LOGIN

The SELinux user sysadm_u is able to X Windows login.

NETWORK

The SELinux user sysadm_u is able to listen on the following tcp ports.

all ports with out defined types

The SELinux user sysadm_u is able to listen on the following udp ports.

ntp_port_t: 123

all ports with out defined types

The SELinux user sysadm_u is able to connect to the following tcp ports.

all ports

BOOLEANS

SELinux policy is customizable based on least access required. sysadm_t policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sysadm_t with the tightest access possible.

If you want to allow users to connect to mysql, you must turn on the allow_user_mysql_connect boolean.

setsebool -P allow_user_mysql_connect 1

If you want to allow user processes to change their priority, you must turn on the user_setrlimit boolean.

setsebool -P user_setrlimit 1

If you want to control users use of ping and traceroute, you must turn on the user_ping boolean.

setsebool -P user_ping 1

If you want to allow w to display everyone, you must turn on the user_ttyfile_stat boolean.

setsebool -P user_ttyfile_stat 1

If you want to allow regular users direct dri device access, you must turn on the user_direct_dri boolean.

setsebool -P user_direct_dri 1

If you want to allow user to r/w files on filesystems that do not have extended attributes (FAT, CDROM, FLOPPY), you must turn on the user_rw_noexattrfile boolean.

setsebool -P user_rw_noexattrfile 1

If you want to allow users to run TCP servers (bind to ports and accept connection from the same domain and outside users) disabling this forces FTP passive mode and may change other protocols, you must turn on the user_tcp_server boolean.

setsebool -P user_tcp_server 1

If you want to allow regular users direct mouse access, you must turn on the user_direct_mouse boolean.

setsebool -P user_direct_mouse 1

If you want to allow users to connect to PostgreSQL, you must turn on the allow_user_postgresql_connect boolean.

setsebool -P allow_user_postgresql_connect 1

HOME_EXEC

The SELinux user sysadm_u is able execute home content files.

TRANSITIONS

Three things can happen when sysadm_t attempts to execute a program.

1. SELinux Policy can deny sysadm_t from executing the program.

2. SELinux Policy can allow sysadm_t to execute the program in the current user type.

Execute the following to see the types that the SELinux user sysadm_t can execute without transitioning:

sesearch -A -s sysadm_t -c file -p execute_no_trans

3. SELinux can allow sysadm_t to execute the program and transition to a new type.

Execute the following to see the types that the SELinux user sysadm_t can execute and transition:

$ sesearch -A -s sysadm_t -c process -p transition

COMMANDS

semanage login
can also be used to manipulate the Linux User to SELinux User mappings

semanage user
can also be used to manipulate SELinux user definitions.

system-config-selinux
is a GUI tool available to customize SELinux policy settings.
